지정한 규칙과 사용자 및 AccessControlType(허용 또는 거부)이 같은 모든 액세스 제어 규칙을 검색하여 제거합니다.

public:
 void RemoveAccessRuleAll(System::Security::AccessControl::MutexAccessRule ^ rule);

public void RemoveAccessRuleAll (System.Security.AccessControl.MutexAccessRule rule);

override this.RemoveAccessRuleAll : System.Security.AccessControl.MutexAccessRule -> unit

Public Sub RemoveAccessRuleAll (rule As MutexAccessRule)

매개 변수

rule

MutexAccessRule

검색할 사용자 및 MutexAccessRule을 지정하는 AccessControlType입니다. 이 규칙에서 지정한 모든 권한은 무시됩니다.

예외

ArgumentNullException

rule이(가) null인 경우

예제

다음 코드 예제에서는 메서드가 RemoveAccessRuleAll 사용자와 AccessControlType일치하는 모든 규칙을 제거하고 권한을 무시하는 것을 보여 줍니다.

이 예제에서는 개체를 MutexSecurity 만들고, 현재 사용자에 대한 다양한 권한을 허용 및 거부하는 규칙을 추가한 다음, 추가 권한을 Allow 규칙에 병합합니다. 그런 다음, 현재 사용자가 소유권을 가져올 수 있도록 하는 새 규칙을 만들고 해당 규칙을 사용하여 개체에서 MutexSecurity 규칙을 제거 Allow 합니다.

참고

이 예제에서는 보안 개체를 개체에 Mutex 연결하지 않습니다. 보안 개체를 연결하는 예제는 다음에서 Mutex.GetAccessControl Mutex.SetAccessControl찾을 수 있습니다.

설명

현재 MutexSecurity 개체는 사용자와 값rule이 같은 AccessControlType 규칙을 검색합니다. 이 검색을 수행할 때 지정된 rule 모든 권한은 무시됩니다. 일치하는 규칙을 찾을 수 없으면 아무 작업도 수행되지 않습니다.
